JAMES J. DOYLE, O'F SHARON, OONNEGTIOUT.

IMPROVED BEEFSTEAK-CRUSHER.

Specification forming vpart of Letters Patent No. 50,921, dated November 14, 186.5.

To all whom it may concern:

Be it known that I, JAMES J. DOYLE, of Sharon, in the county of Litchtleld and State of Oonnecticut, haveinvented a new and useful Improvement in Beel'steak-Orushers; and l do hereby declare that the following is a full, clear, and exact description thereof, which 'will enable those skilled in the art to make and use the same, reference being had to the accom panying` drawings, forming part of this specification, in which- Figure l is a Vertical cross-section through the line w ar, Fig. 2. Fig. 2 is a Vertical longitudinal section through the line 7/ y, Fig'. l.

The object of my inveution is to furnish an instrument by means of which beafsteak may be made tender and prepared for coohing without being1 mashed into a shapcless mass; and it consists of combining` two cylinders whose surfaces are covered with teeth made in the form of truncated square pyramids with each other and with the frame in which they are placed, as hereinafter more fully described.

A is the toumlation-board or table to which the instrument is attached or upon which it stands.I

is the frame of the crusher, the feet O of which maybe screwcd fast to the board or table A.

D is a rod or bar, by means of which the upper cnd of the frame B is held in position. The lower roller or cylinder, E, revolves in bearings F in the sides of the frame B.

To the end Gr of the axle of the cylinderE is attached a crank, by means of which the cylinder E is revolved. The cylinder H revolves in adjustable bearings I iu the sides of the frame B. The blocks which form the bearings I are placed in an opening or slot in the sides of the frame B.

Upon the parts of the frame B which form the sides of the slots in which the bearings I are placed are formed a series of corrugations, J. The blocks which form the bearings I have shoulders projecting over the corrugations J,

the under side of which shoulders are corrugated to coi'respond to said corrugations, as shown at I, Fig. 2.

The blocks which form the beariugs I are held in place by bolts which pass through the said projecting shoulders of the blocks and through the sides of the frame B, said projecting` shoulder being' slotted, as represented at K, Fig. 1, to allow said blocks to be moved up or down, as required; but the bearings I may be made adj ustable by meansofa spring placed between the blocks and the upper side of the slots in which said blocks are placed, the ends of the blocks working up and down in grooves iu the sides of the frame B. In this case the corrug'atious J and the projecting shoulders of the blocls will be left off and the outer side ot' the blocks made flush with the outer sides of the frame B. This latter mode of adjustment I prefer, as it enables the instrument to adjust itself to the Variations in thickness of the steak which may be passing' between the rollers.

The teeth or 1 rojectious L ot' the cylinders E and H are made iu the form of truncated square pyramids, arrang'ed in rows, with a space between the adjacent teeth about cqual to the base of each tooth, the teeth of each row being placed opposite the spaces o t' the previous row. The teeth of the cylinder H mesh into the teeth of the cylinder E, and in this way motion is given to the cylinder H.

Vhat I claim as new, and desire to secure by Letters Patent, is-- A beefisteak-crusher formed by combining` the cylinders E and H, constructed substantially as dcscribed, with each other and with the frame B, substantially as described, and for the purpose set forth.

The above specification ot' my invention signed by me this 6th day of October, 1865.

JAMES J. DOYLE.
